Can you share the php snippet of your theme block? I don't know what the issue is, haven't seen it before.

Strange, for me it works exactly as expected. I can change the value and it gets updated. Updating client does not change anything, because your block uses the other setting. But I don't see any errors.

Are you using the latest version?

[aditya-wiguna]
